About 35,000 spectators went through the gates yesterday, with a total of about 50,000 during the three-day racing event.
Taupo resident Phil Tataurangi took his 8-year-old son Kahu, his son's friend Louie Love-Parata and nephews Jacob, 11, and Luke Robinson, 12, to watch the racing yesterday.
He said they probably didn't know who any of the drivers were but they were big sports and car fans so it didn't matter.
"The kids are just buzzing about being here. They got a kick out of seeing all the Ferraris parked out the back."
Alan Wright-St Clair, who came to Taupo from Waihi with his fox terrier Paddy in his housevan, got all but one of the 19 drivers' autographs during the driver signing session after the sprint race.
He was told Brazil's Felipe Guimaraes was sleeping during the public signing session.
And despite being decked out in matching orange shirts to Netherlands drivers Dennis Retera and Robert Doornbos, Dutch couple Katja and Evan Bouw lined up to get Team New Zealand driver Chris van der Drift's autograph.
Meanwhile, Formula One hopeful 19-year-old Brendon Hartley took Opshop singer Jason Kerrison for a few laps in a Toyota Racing Series race car.
Thrill-seeking Kerrison said the ride, which reached speeds of 220km/h, didn't scare him as much as having to sing the national anthem before the feature race.
"I'll have to go away and rest my voice, it's getting a bit hoarse from all the screaming."
Police made no arrests throughout the event and St John Ambulance staff only treated people with heat-related illnesses and allergies.
